In a method for producing a catalyst layer (1) for fuel cells, chemical or electrochemical reactors using a precursor layer, which comprises a plurality of electrically conductive precursor particles (3, 4), a catalyst (2) being electrochemically deposited, the catalyst layer (1) is produced as a structured layer. This is achieved by the targeted inhomogeneous selection of the precursor particles (3, 4) with regard to at least one particle property, by the addition of non-conductive particles and/or at least one chemical additive to the precursor layer, and/or in that significant amounts of gas are produced in the catalyst layer or conveyed through said layer before, during, or after the electrochemical deposition. |
